Actual situations evidence how adopted decisions can change the decision constraints of the system where the analytic hierarchy process (AHP) is being applied. Therefore, the purpose of this paper is to provide a dynamic view of the AHP method, considering the criteria and alternatives as temporary variables and finally obtaining not only one good choice for a specific moment but a more comprehensive picture of those alternatives resulting more important for the business, according to strategy and over time.

With this purpose this paper starts with a short literature review and the general characteristics of the AHP method. Afterwards, the paper presents the problem that appears frequently in actual situations which justify the development of this research. Once described, the uncertainty appeared after the AHP implementation, the proposed methodology called dynamic analytic hierarchy process (DAHP) is presented.

Finally, this paper shows a case study and concludes with the main points of the research suggesting applications and further extensions.

The value of this paper is the description of a DAHP as a tool that can facilitate decision making related to some of the critical aspects in maintenance or post-sales area, permitting the alignment of actions with the business’ objectives.

The purpose of this paper is to propose a methodology for the engineering of E-maintenance platforms that is based on a value-driven approach.

The methodology assumes that a value-driven engineering approach would help foster technological innovation for maintenance management. Indeed, value-driven engineering could be easily adopted at the business level, with subsequent positive effects on the industrial applications of new information and communication technologies solutions.

The methodology combines a value-driven approach with the engineering in the maintenance scope. The methodology is tested in a manufacturing case to prove its potential to support the engineering of E-maintenance solutions. In particular, the case study concerns the investment in E-maintenance solutions developed in the framework of a Supervisory Control and Data Acquisition system originally implemented for production purposes.

Based on literature research, the paper presents a methodology that is implemented considering three different approaches (business theories, value-driven engineering and maintenance management). The combination of these approaches is novel and overcomes the traditional view of maintenance as an issue evaluated from a cost-benefit perspective.

The purpose of this paper is to present a brief summary of quality and contractual aspects for the improvement of the warranty management. Together with this, the present work will show also some of the best practices followed by companies in order to manage properly those kinds of issues related to warranty, as well as some indications to assess the implementation degree of such practices in the whole organization. Basically, the global objective of the study is to present to the reader and in few words the importance of taking into account legal and quality aspects, when a company offers a technical service for the warranty assistance of any of its products, together with the maturity level that this company achieves applying some best practices currently available.

The study starts by mentioning some antecedents related to warranty, in order to summarize a reference framework, proposed for proper warranty management, and how the information exchange should be performed among the different departments of a generic company. Then, it will be suggested how to apply this according to a strategic management which is divided in phases, taken from the product life cycle concept: Front‐end, Design and Development, Production, Marketing, and Post‐sale Support. These phases are included in three higher stages considered as Pre‐Launch stage, Launch and Post‐Launch stage, where different decisions play important roles. Afterwards, it will be shown how warranty management is viewed from the contract and legal point of view, in order to link the above mentioned topics on generic management, with those best practices currently presented in actual markets. Finally, once analysed, all those aspects related to best practices and its application on the reference framework, it is required now to quantify how a company manages the warranty assistances by a maturity assessment on warranty management.

The paper observes what today's companies are doing in this field, that is, their best practices in warranty management covering the quality and contractual aspects already mentioned, in order to round off the development of a completed framework for such management.

The paper presents a review, a framework and a practical application of the framework for the management of warranty contracts, including a maturity assessment or evaluation.

In recent years there has been a marked increase in the consumption of bottled wine in the United States. Associated with this phenomenon, there has been a substantial rise in the number of vineyards from foreign countries entering this competitive market. The study examines the factors that influence wine prices. Specifically, the article proposes that the country of origin, the perceived quality and the varietal of the wine have an effect on wine price in favour of countries with greater wine traditions. These premises were tested by means of a multiple regression model estimated using a sample drawn from the North American market. The study concluded that this market recognises differences in country of origin, quality and varietal. Specifically, these factors significantly influence wine prices, with price premiums being awarded to wines of varietal Pinot and to wines produced in France.

This paper aims to investigate associations between firm resources and reliance on entrepreneurial marketing (EM) channels among agrofood ventures. It accounts for agropreneur gender and racial/ethnic status in the context of marketing channel portfolio composition. The authors examine the established assumption that resource limitations drive EM and whether socially disadvantaged status of agropreneurs is associated with marketing strategy beyond standard resourcing measures.

Using 2015 Local Foods Marketing Practices Survey data, the authors apply linear regression to investigate differences in the use of EM channels, accounting for resources, social status and other factors.

Limited-resource ventures rely more on consumer-oriented channels that require EM practices. Socially disadvantaged entrepreneurs favor these channels, even when accounting for resources. Notably, ventures headed by men of color rely more on the most customer-centric local foods marketing channel.

Future research should investigate how social and human capital influences the use of EM.

Entrepreneurial support policy and practice for agropreneurs should be cautious about the “double-burden” folk theorem of intersectional disadvantage and review how to best direct resources on EM to groups most likely to benefit.

This paper uses a unique, restricted, nation-wide, federal data set to examine relationships between resource endowments, social status and the composition of agrofood enterprises’ marketing channel portfolios. To the best of the authors’ knowledge, it is the first to include racial- and ethnic-minority status of agropreneurs and to account for intersectionality with gender.

The concept of sustainable development (SD) is a popular response to society’s need to preserve and extend the life span of natural resources. One of the 17 goals of the SD is “education quality” (Fourth Goal of Sustainable Development [SDG-4]). Education quality is an important goal because education is a powerful force that can influence social policies and social change. The SDG-4 must be measured in different contexts, and the tools to quantify its effects require exploration. So, this study aims to propose a statistical model to measure the impact of higher education online courses on SD and a structural equation model (SEM) to find constructs or factors that help us explain a sustainability benefits rate. These proposed models integrate the three areas of sustainability: social, economic and environmental.

A beta regression model suggests features that include the academic and economic opportunities offered by the institution, the involvement in research activities and the quality of the online courses. A structural equation modelling (SEM) analysis allowed selecting the key variables and constructs that are strongly linked to the SD.

One of the key findings showed that the benefit provided by online courses in terms of SD is 62.99% higher than that of offline courses in aspects such as transportation, photocopies, printouts, books, food, clothing, enrolment fees and connectivity.

The SEM model needs large sample sizes to have consistent estimations. Thus, despite the obtained estimations in the proposed SEM model being reliable, the authors consider that a limitation of this study was the required time to collect data corresponding to the estimated sample size.

This study proposes two novel and different ways to estimate the sustainability benefits rate focused on SDG-4, and machine learning tools are implemented to validate and gain robustness in the estimations of the beta model. Additionally, the SEM model allows us to identify new constructs associated with SDG-4.

Academic research has endeavoured to understand women's behaviours in entrepreneurial activity, identifying the differences when compared to men. The main topics analysed show similar findings in relation to characteristics and motivations, leadership style, strategic choice, obstacles and results. This paper delves further into these differences by examining the personal characteristics of entrepreneurs, the motivation to enter the activity and the performance of their enterprises. The paper aims to discuss these issues.

The authors study Spanish entrepreneurial activity using a survey carried out in 2009 of 608 randomly selected entrepreneurs. The main methods used are descriptive analyses and logistic estimations.

There were two groups of entrepreneurial women with different profiles and results: the first group comprises a variety of sectors reflecting the economy's average; and the second mainly operates in those sectors traditionally considered as female. Male and female reasons for success and survival are found to be substantially the same, but personal characteristics and motivations were found to be different. Among the differences found, it is worth highlighting the amount of time devoted by entrepreneurial women to household chores, the higher proportion of women in the staff they employ, and their commitment to product and service innovation.

The findings point to some ideas in terms of policies regarding entrepreneurial activity and gender. The women's greater commitment to innovation in goods and services suggests new approaches in policies aimed at promoting the entry of women in entrepreneurial activity.

The main findings of the paper are consistent with relevant existing literatures, but the results offer new insights that contribute to improving the knowledge of the dynamics of entrepreneurial women.

This article conceptualizes essential keys to the future of peer reference in academic libraries as extrapolated through the dual lenses of academic library history in the United States of America and recent experiences of a peer program with prospective and actual out-of-the-building experiences.

A 30,000-foot historical view of the dispositions of space in academic library buildings, collections, spaces, technology and reference provision is integrated with a description of the responses and insights of a peer reference program during the program's prospective and actual out-of-the-building experiences. These components are then analyzed to extrapolate keys to peer reference provision in any learning environment.

Peer reference is a natural extension of the Learning Commons model as developed in many academic libraries. To find optimal success in leveraging the benefits of peer-to-peer learning, program coordinators should keep in mind the social aspects of peer learning and intentionally articulate a framework for service delivery that best matches the modalities of providers, patrons and the information environment. In reviewing training and service practices, coordinators should be particularly on guard for any bias due to traditional reliance on the affordances of a library building and/or physical service point.

This article founds its conclusions in regard to the future of peer reference by contextualizing the evolution and future of such programs in the wider historical context of academic library dispositions of space in support of learning. It proposes a conceptual framework for intentionally matching the modalities of providers, patrons and the information environment.
